For drug courts to be most effective, judges, court personnel, treatment providers, and treatment coordinators partner together to assist in the development of treatment, rehabilitation, and supervision plans for each defendant based on a clinical assessment or diagnostic process. Lengths of stay in treatment and in aftercare are factors associated with positive outcomes and, in particular, with the cessation of drug use, reduction in recidivism rates, and improvement in educational and employment status and family relationships. In coordination with the drug court judge and other court personnel, treatment and case management personnel assess clients' treatment needs, track their progress in treatment programs, and determine appropriate levels of treatment services. Supportive social services provide drug court staff with links to employment, educational/vocational placement, family counseling, and housing placement assistance for drug court participants.
